HU SKING-TROUGH FOR CORN-HUSKING MACHINES.

SPECIFICATION forming part of Letters Patent No. 669,687, dated March 12, 1901.

Application filed July 24, 1900- cerial No. 24,648. (No model.)

To all whom it may concern:

Be it known that I, HENRY L. FERRIS, a citizen of the United States of America, residing at Harvard, in the county of McHenry and State of Illinois, have invented certain new and useful Improvements in Husking- Troughs for Corn Husking Machines, of which the following is a specification.

My invention relates to certain improvements in huskingtroughs for corn-husking machines, designed to render the working of said machines more certain and effective and to remedy certain defects in the operation of the same.

In the ordinary husking-machine, in which the husk is stripped from the ear by means of a pair of rolls arranged too close together to allow the corn to pass through with the husk, it is necessary to make a trough above the rolls of sufficient storage capacity to accommodate a quantity of unhusked ears, which may be fed to the husker at one time. It is also necessary that the lower portion of the trough be wide enough to afford a free passage for the ears to the rolls. Difficulty has been encountered in constructions of this sort because of the passage of some of the ears downward along the sides of the trough without being husked. This difficulty I have aimed to obviate by certain mechanism herein described, the essential features of which are pointed out in the claims appended hereto. The invent-ion is illustrated by means of four views shown in the drawings, of which Figure l is a plan of the basking-trough and husking-rolls; Fig. 2, a longitudinal vertical section in line 2 2 of Fig. 1; Fig. 8, an end elevation of the lower end of the trough; and Fig. 4, a detail of a wing or cleat, the use of which will be described below.

Referring to the drawings, A is a suitable framework, upon which are supported bearings a a, in which are journaled a pair of husking-rolls B B. In an inclined position above it are arranged side boards 0 0, forming a trough in which the unhusked ears of corn are dropped. Upon the inner sides of these boards are secured a series of wings or cleats 0, extending to the lower edge adjacent to the rolls and projecting inward into the trough, so as to block the passage of the ears longitudinally of the latter except in the central portion, where they are operated upon by a series of projecting pins 0' and sockets c registering therewith, upon the respective rolls. In the operation of these rolls if the corn is fed into the trough faster than it can pass down the middle portion thereof the portions along the side boards are held until those in the middle pass out of the way and are then brought to the middle by the rotation of the rolls. This absolutely prevents the passage of any unhusked ears down along the side boards and at the same time provides ample capacity in the trough for the temporary overload.

The exact construction of the wings is, to a certain extent, immaterial; but I prefer to form them by bending a piece of sheet metal into the form of a corner an gle-plate provided with holes 0 by means of which one of the flanges may be secured to the side board.

I claim as new and desire to secure by Letters Patent 1. In a husking-machine, the combination with a pair of husking-rolls, the upper surfaces of which rotate toward each other, of a pair of side boards approximately parallel with said rolls and forming, together with the latter, an inclined trough, down which the corn passes by gravity, and a series of stops projecting inward from theinner sides of the side boards, approximately parallel with the line of movement of the rolls and transverse to that of the corn whereby any surplus corn which lodges along the sides of the trough is held against longitudinal movement until carried from behind the stops by the rotation of the rolls; substantially as described.

2. In a husking-machine, the combination with a pair of husking-rolls turning toward each other, of a pair of side boards above the same provided with stops projecting inwardly and adapted to check and hold the corn which lodges along the sides of the trough until the center of the trough is free and the corn is picked up and carried to the center by the rolls; substantially as described.

In witness whereof I have hereunto set my hand, at Harvard, in the county of McHenry and State of Illinois, this 15th day of June, A. D. 1900.

HENRY L. FERRIS.
